Bariatric surgery is just the first step in a lifelong commitment toward better health. When deciding if weight loss surgery is right for you, keep in mind that surgery is only tool. Your ultimate success depends on strict adherence to the recommended dietary, exercise and lifestyle changes. The goal is to live better, healthier and longer.  After reviewing all the information and attending one of the free educational seminars with the New Jersey Bariatric Center® team, you’ll need to decide if you are ready to make that commitment.

New Jersey Bariatric Center® performs three surgeries that have resulted in successful weight loss and improved health for our patients: gastric bypass, gastric sleeve (also called a sleeve gastrectomy) and gastric band (LAP-BAND®). Not all bariatric surgery procedures are the same. If you qualify for weight loss surgery (visit Do I Qualify?), the New Jersey Bariatric Center team will guide you in deciding which procedure will give you the best chance for success based on factors such as your current weight and your ability to follow the post-surgical guidelines. Here is a side-by-side look at each procedure:

     

How the procedure is done

Gastric Bypass

In a gastric bypass, a portion of the stomach is stapled off to create a small pouch that is then connected to the lower portion of the intestine, allowing food to bypass a portion of the digestive tract. The newly formed pouch can hold about 4 oz. of food.

Gastric Band
(Lap-Band®/Realize®)

An adjustable band is placed around the upper part of the stomach, creating a small pouch that holds about a half-cup of food. 

Gastric Sleeve

During the sleeve gastrectomy, a thin vertical sleeve about the size of a banana is created from the stomach using a stapling device. The rest of the stomach is removed. The newly shaped stomach can hold about a cup of food.

How it helps you lose weight

Gastric Bypass

Bypass is the only one of the three procedures that affects both the amount of food you can eat and the way your body absorbs it.  The surgery limits the amount of food that can be eaten at one time and also decreases hunger hormones, so you feel full sooner and stay that way longer. Bypass patients absorb fewer calories as well. Your body will stop storing excess calories and start using its fat supply for energy.

Gastric Band
(Lap-Band®/Realize®)

The smaller stomach pouch limits the amount of food that can be eaten at one time. You’ll feel full sooner and stay full longer. As you eat less food, your body will stop storing excess calories and start using its fat energy supply.

Gastric Sleeve

The smaller stomach pouch limits the amount of food you can eat at one time leaving you feeling fuller sooner and longer. The procedure also decreases your levels of hunger hormones so you feel less hungry. As you eat less food, your body will stop storing excess calories and start using its fat supply for energy.

Reversible

Gastric Bypass

No

Gastric Band
(Lap-Band®/Realize®)

Yes, but keep in mind that patients who have the band removed typically gain the weight back.

Gastric Sleeve

No

Length of hospital stay and recovery time

Gastric Bypass

NJBC's bypass patients typically spend two nights in the hospital and return to normal activity - walking, climbing stairs, etc. - a few days after surgery. Patients are advised to take two weeks off before returning to work to adjust to the new lifestyle that is required with all weight loss surgeries. Those who are unable to take that much time off can return to work earlier, as long as their work does not require heavy lifting (anything over 15 lbs.), but this is not the norm.

Gastric Band
(Lap-Band®/Realize®)

NJBC's band patients typically go home the same day of surgery and return to normal activity - walking, climbing stairs, etc. - a few days after surgery. Patients are advised to take two weeks off before returning to work to adjust to the new lifestyle that is required with all weight loss surgeries. Those who are unable to take that much time off can return to work earlier, as long as their work does not require heavy lifting (anything over 15 lbs.), but this is not the norm.

Gastric Sleeve

NJBC's sleeve patients can expect to spend one to two nights in the hospital and return to normal activity - walking, climbing stairs, etc. - a few days after surgery. Patients are advised to take two weeks off before returning to work to adjust to the new lifestyle that is required with all weight loss surgeries. Those who are unable to take that much time off can return to work earlier, as long as their work does not require heavy lifting (anything over 15 lbs.), but this is not the norm.

Laparoscopic vs. open surgery

Gastric Bypass

All weight loss procedures at NJBC are performed through minimally invasive laparoscopic surgery, in which surgical instruments are inserted through four to five small incisions. This replaces the need for one long incision to open the abdomen. The result is less pain and easier breathing and lung functioning after surgery. Laparoscopy also results in a shorter hospital stay and fewer wound complications such as infection, scarring or hernia. New Jersey Bariatric Center surgeons were the first in New Jersey to perform single incision laparoscopic band surgery, in which surgery is performed though one incision around the belly button. The surgeons will determine whether you are a candidate for single incision surgery. If not, traditional laparoscopic surgery is performed.

Weight loss

Gastric Bypass

Initial weight loss with the gastric bypass is approximately 3 lbs. to 5 lbs. per week for the first 3 to 6 months. Over 18 months, a gastric bypass can result in the loss of about 65 percent to 70 percent of excess weight. That means that a patient who is 100 pounds overweight typically loses 65 lbs. to 70 lbs.

Gastric Band
(Lap-Band®/Realize®)

Patients who've had the LAP-BAND® or REALIZE® band procedure usually lose about 1 lb. to 2 lbs. a week. Over an 18-month period, patients can see a loss of about 50 percent to 55 percent of excess weight. For a person who is 100 pounds overweight, that means an overall weight loss of 50 lbs. to 60 lbs.

Gastric Sleeve

Patients typically lose 2 lbs. to 4 lbs. a week after sleeve gastrectomy, with a total excess weight loss of up to 55 percent to 65 percent over an 18-month period.  That means a patient who is 100 pounds overweight typically loses 55 lbs. to 65 lbs.

Dietary and lifestyle changes

Gastric Bypass

All weight loss surgery patients have to learn completely new eating habits. Your meal sizes will be drastically reduced. Most people cannot tolerate dry, solid foods like steak and certain foods, like rice, will be off limits. Sugary foods – such as soda, juice and fruits - should be avoided, as should high-fat sweets such as ice cream. When you eat properly, you’ll feel full longer so the desire to snack between meals will be eliminated, even with your much smaller meal size. Patients are told to eat three small meals a day and one snack. Not only will old eating habits change but sedentary lifestyles will have to change as well. NJBC patients who routinely engage in physical activities have the best long-term results. After their initial weight loss, many find enjoyment in exercise for the first time in their lives and dive into it in a way they never believed was possible.
